Diamond Hill Short Duration Income Fund | Asset-Backed, Mortgage-Related and Mortgage-Backed Securities Risk  
Prospectus [Line Items]  
Risk [Text Block]

Asset-Backed, Mortgage-Related and Mortgage-Backed Securities Risk Asset-backed, mortgage-related and mortgage-backed securities, including so-called “sub-prime” mortgages, are subject to certain risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid.

 

CMOs and stripped mortgage-backed securities, including those structured as interest only (“IOs”) and principal only (“POs”), are more volatile and may be more sensitive to the rate of prepayments than other mortgage-related securities. CMOs are issued in multiple classes, and a class with an earlier final payment date may have certain preferences in receiving principal payments or earning interest. As a result, the value of some classes in which the Fund invests may be more volatile and may be subject to higher risk of non-payment. The risk of default for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities.

 

The values of IO and PO mortgage-backed securities are more volatile than other types of mortgage-related securities. They are very sensitive not only to changes in interest rates, but also to the rate of prepayments. In addition, because there may be a drop in trading volume, an inability to find a ready buyer, or the imposition of legal restrictions on the resale of securities, these instruments may be illiquid. The Fund will be exposed to additional risk to the extent that it uses inverse floaters and inverse IOs. These securities are more volatile and more sensitive to interest rate changes than other types of debt securities. If interest rates move in a manner not anticipated by the Adviser, the Fund could lose all or substantially all of its investment in inverse IOs.

Diamond Hill Short Duration Income Fund | Consumer Loans Risk  
Prospectus [Line Items]  
Risk [Text Block]

Consumer Loans Risk Investments in consumer loans expose the Fund to additional risks beyond those normally associated with more traditional debt instruments. The Fund’s ability to receive payments in connection with the loan depends primarily on the financial condition of the borrower and whether or not a loan is secured by collateral, although there is no assurance that the collateral securing a loan will be sufficient to satisfy the loan obligation. In addition, bank loans often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price. Transactions involving bank loans may have significantly longer settlement periods than more traditional investments (settlement can take longer than 7 days) and often involve borrowers whose financial condition is troubled or highly leveraged, which increases the risk that the Fund may not receive its proceeds in a timely manner or that the Fund may incur losses in order to pay redemption proceeds

to its shareholders. In addition, loans are not registered under the federal securities laws like stocks and bonds, so investors in loans have less protection against improper practices than investors in registered securities.

Risk [Text Block]

Credit Risk There is a risk that issuers and counterparties will not make payments on securities and repurchase agreements held by a fund. Such default could result in losses to the Fund. In addition, the credit quality of securities held by the Fund may be lowered if an issuer’s financial condition changes. Lower credit quality may lead to greater volatility in the price of a security and in shares of the Fund. Lower credit quality also may affect liquidity and make it difficult for the Fund to sell the security.

Diamond Hill Short Duration Income Fund | Current Market Environment Risk

Risk [Text Block]

Current Market Environment Risk Various sectors of the financial markets may experience an extended period of adverse conditions. Market uncertainty can increase dramatically, and these conditions may result in disruptions of the equity markets, periods of reduced liquidity, greater general volatility, and a contraction of availability of credit and lack of price transparency. In particular, certain types of securitized bond investments may come under stress due to economic factors and trends, such as higher than expected interest rates, property vacancies and consumer stress.

Diamond Hill Short Duration Income Fund | Government Securities Risk  
Prospectus [Line Items]  
Risk [Text Block]

Government Securities Risk The Fund may invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities. These securities may be backed by the credit of the government as a whole or only by the issuing agency. U.S. Treasury bonds, notes, and bills and some agency securities, such as those issued by the Federal Housing Administration and Ginnie Mae, are backed by the full faith and credit of the U.S. government as to payment of principal and interest and are the highest quality government securities. Other securities issued by U.S. government agencies or instrumentalities, such as securities issued by the Federal Home Loan Banks and Freddie Mac, are supported only by the credit of the agency that issued them, and not by the U.S. government. Other securities issued by U.S. government agencies or instrumentalities are supported by the agency’s right to borrow money from the U.S. Treasury under certain circumstances, but are not backed by the full faith and credit of the U.S. government. No assurance can be given that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law.

Diamond Hill Short Duration Income Fund | High Yield Securities Risk  
Prospectus [Line Items]  
Risk [Text Block]

High Yield Securities Risk The Fund will purchase fixed income securities rated below the investment grade category. Securities in this rating category are speculative. Changes in economic conditions or other circumstances may have a greater effect on the ability of issuers of these securities to make principal and interest payments than they do on issuers of higher grade securities.

Diamond Hill Short Duration Income Fund | Inflation Risk  
Prospectus [Line Items]  
Risk [Text Block]

Inflation Risk Because inflation reduces the purchasing power of income produced by existing fixed income securities, the prices at which fixed income securities trade will be reduced to compensate for the fact that the income they produce is worth less. This potential decrease in market value would be the measure of the inflation risk incurred by the Fund.

Interest Rate Risk The Fund invests in fixed income securities. These securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund’s fixed income securities generally declines. On the other hand, if rates fall, the value of the fixed income securities generally increases. Your investment will decline in value if the value of the Fund’s investments decreases.

Diamond Hill Short Duration Income Fund | Liquidity Risk  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk The Fund may not be able to purchase or sell a security in a timely manner or at desired prices or achieve its desired weighting in a security. Liquidity risk may result from the lack of an active market or a reduced number and capacity of traditional market participants to make a market in fixed income securities, and may be magnified during times of market stress. The Fund may not be able to meet the requests to redeem Fund shares without significant dilution of remaining investors’ interest in the Fund.

Diamond Hill Short Duration Income Fund | Management Risk

Management Risk The Adviser’s judgments about the attractiveness, value, and potential appreciation of a particular asset class or individual security in which the Fund invests may prove to be incorrect, and there is no guarantee that individual investments will perform as anticipated.

Diamond Hill Short Duration Income Fund | Market Risk  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk The value of the Fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the Fund, particular industries or overall securities markets. When the value of the Fund’s investments goes down, your investment in the Fund decreases in value. A variety of factors including interest rate levels, recessions, inflation, U.S. economic growth, war or acts of terrorism, natural disasters, political events, supply chain disruptions, trade barriers, staff shortages and widespread public health issues affect the securities markets. These events may cause volatility, severe market dislocations and liquidity constraints in many markets, including markets for the securities the Fund holds, and may adversely affect the Fund’s investments and operations. In addition, governmental responses to these events may negatively impact the capabilities of the Fund’s service providers, disrupt the Fund’s operations, result in substantial market volatility and adversely impact the prices and liquidity of the Fund’s investments.

Diamond Hill Short Duration Income Fund | Non-U.S. and Emerging Markets Risk  
Prospectus [Line Items]  
Risk [Text Block]

Non-U.S. and Emerging Markets Risk The Fund may invest in non-U.S. securities and U.S. securities of companies domiciled in non-U.S. countries. As a result, the Fund may experience more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies. These companies may be subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible non-U.S. controls on investments, and less stringent investor protection and disclosure standards. Trade tensions and sanctions on individuals and companies can contribute to market volatility, which may affect the Fund’s performance. These risks are magnified in emerging markets as events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. The market for the

securities of issuers in emerging markets is typically small and low, and nonexistent trading volumes in those securities may result in a lack of liquidity and price volatility.

Diamond Hill Short Duration Income Fund | Prepayment and Call Risk  
Prospectus [Line Items]  
Risk [Text Block]

Prepayment and Call Risk The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.
